Objective:To investigate the association between quantitative CT-derived hip bone mineral density (BMD) and all-cause mortality in elderly women after hip fracture surgery.Methods:A retrospective study was conducted to analyze the clinical data of the 254 elderly women with hip fracture who had been surgically treated at Department of Orthopaedics and Traumatology, Shunyi District Hospital between December 2018 and December 2019. Their average age was (79.3±7.7) years. There were 128 femoral neck fractures and 126 intertrochanteric fractures. CT images of their proximal femurs on the healthy side were analyzed using quantitative CT Pro software to assess the BMDs at the femoral neck, greater trochanter, intertrochanteric region, and total hip. The primary endpoint was all-cause mortality during follow-up. The patients were classified into a death group and a censored group (survivors and those lost to follow-up). The secondary outcome was recovery of pre-fracture ambulation. Multivariable Cox proportional hazards regression was performed to evaluate the association between regional hip BMD and mortality risk.Results:Of the patients, 236 obtained a follow-up of 36.9 (32.7, 42.6) months and 18 were lost to the follow-up. A total of 28.3% (72/254) of the patients died within 3 years after surgery. The overall hip BMD [(0.510 9±0.094 3) g/cm 2], the greater trochanter BMD [(0.351 0±0.079 6) g/cm 2], and the intertrochanteric BMD[(0.629 5±0.116 9) g/cm 2] in the death group were significantly lower than those in the censored group [(0.565 8±0.104 1) g/cm 2, (0.398 6±0.092 1) g/cm 2, and (0.685 6±0.126 6) g/cm 2]( P<0.05). The multivariate Cox regression analysis showed that a lower BMD at all hip sites measured was significantly associated with a higher mortality risk before adjustments ( P<0.05), but after confounding variables were adjusted, only the greater trochanter BMD ( HR=1.789, 95% CI: 1.035 to 3.092, P=0.037) and the intertrochanteric BMD ( HR=1.758, 95% CI: 1.018 to 3.037, P=0.043) were significantly associated with a higher mortality risk. Furthermore, follow-ups showed that 54 patients (56.3%, 54/96) in the high trochanter BMD group regained their pre-fracture ambulatory status, significantly more than the 22 patients in the low BMD group (32.4%, 22/68), showing an increased odds of ambulation recovery ( OR=2.688, 95% CI: 1.405 to 5.143, P=0.003). Conclusion:In elderly women with hip fracture, quantitative CT-derived measurement of the hip BMD, particularly in the trochanteric region, can serve as an early warning indicator of all-cause mortality after hip fracture surgery.

Objective:To study the health-related quality of life (HRQOL) and influencing factors of echinococcosis surgical patients included in the project management in Jingyuan County since the implementation of the Central Transfer Payment for Local Echinococcosis Prevention and Control Project (hereinafter referred to as the Echinococcosis Prevention and Control Project).Methods:Surgical patients included in the management of Echinococcosis Prevention and Control Project in Jingyuan County from January 1, 2009 to December 31, 2022 were selected as study subjects for a door-to-door questionnaire survey to collect basic information, medical treatment and diagnosis, surgical situation, postoperative follow-up and management situation, preoperative and postoperative HRQOL. Multivariate logistic regression was employed to analyze the influencing factors of HRQOL in echinococcosis surgical patients.Results:A total of 111 echinococcosis patients undergoing surgery were included, with a first visit duration [ M ( Q1, Q3)] of 8.0 (5.0, 12.0) years from symptom onset to initial consultation, and a surgical treatment duration of 8.0 (5.0, 12.0) years from diagnosis to surgical intervention. The cure rate based on postoperative efficacy observation was 81.08% (90/111). There was no statistically significant differences in the distribution of preoperative and postoperative mobility, self-care, daily activities, anxiety or depression among echinococcosis patients undergoing surgery ( P > 0.05). However, significant differences were observed in the distribution of pain or discomfort and health status scores ( P < 0.001). The results of ordinal logistic regression analysis showed that preoperative age [≥61 years old, OR (95% CI) = 0.06 (0.01, 0.56), P = 0.014], preoperative concomitant hypertension (grade Ⅱ), diabetes, and heart disease [ OR (95% CI) = 13.15 (1.80, 96.13), 57.69 (2.05, 1 620.13), 10.90 (1.27, 93.90), P < 0.05], initial lesion location in the abdominal cavity and the lesion in two or more locations [ OR (95% CI) = 30.83 (1.05, 902.45), 114.25 (7.24, 1 801.75), P < 0.05] were independent influencing factors for preoperative HRQOL in patients with echinococcosis. Postoperative comorbidities of hypertension (grade Ⅱ) and diabetes [ OR (95% CI) = 42.77 (2.39, 766.21), 901.40 (4.64, 1 740.94), P < 0.05], and postoperative complications [ OR (95% CI) = 130.61 (6.27, 2 722.24), P = 0.002] were independent influencing factors for postoperative HRQOL in patients with echinococcosis. Conclusions:The health status of patients with echinococcosis has significantly improved after surgical treatment. Preoperative factors affecting HRQOL of patients with echinococcosis include age, concomitant hypertension, diabetes, heart disease, and the initial lesion location. Postoperative influencing factors include concomitant hypertension and diabetes, as well as postoperative complications.

Objective:To understand the health status of solar greenhouse workers, to provide scientific basis for the development of occupational high incidence diseases prevention and control strategies.Methods:In July 2019, a random cluster sampling method was used to select 245 workers engaged in solar greenhouse vegetable cultivation in Daba Village, Jingyuan County, Baiyin City, Gansu Province as the solar greenhouse operation group. Matched by gender, age, marital status, body mass index (BMI), 282 people from adjacent Shaliang Village who did not engage in solar greenhouse operation were selected as the control group. Field investigation and health examination were carried out among the study subjects. The general situation, facial features examination results, ophthalmic examination results, bone and joint examination results and skin examination results were compared between the two groups. And the multiple logistic regression analysis was used to analyze the influencing factors of abnormal bone and joint examination (upper limbs, lower limbs, hands and spine bone joints) in study subjects.Results:There were statistically significant differences in smoking age and alcohol consumption between the two groups ( P<0.001). Compared with the control group, the abnormal detection rates of nose examination, throat examination, slit lamp examination, conjunctival examination, lower limb bone joint examination, hand bone joint examination, spine examination, head and neck skin examination, trunk skin examination, upper limb skin examination, and lower limb skin examination in the solar greenhouse operation group were higher, and the differences were statistically significant (χ 2=11.53, 7.94, 9.92, 27.93, 79.32, 81.42, 9.43, 6.79, 9.76, 4.34, 8.29, P<0.05). Multivariate logistic regression analysis showed that after adjusting for gender, age, marital status, education level, BMI, compared with the control group, solar greenhouse operation was a risk factor for abnormal bone and joint examination ( OR=1.178, 95% CI: 1.151-2.143, P=0.001) . Conclusion:Solar greenhouse operation has a certain harmful effect on health of workers, and solar greenhouse workers have an increased risk of abnormal diseases of upper limbs, lower limbs, hands and spine bone joints.

Objective:To explore the epidemiological characteristics of geriatric hip fractures in Beijing so as to provide evidence for effective prevention and control measures.Methods:This multicenter study was conducted in 3 urban (Beijing Jishuitan Hospital, Beijing Hospital and Beijing Anzhen Hospital) and 3 suburban hospitals (Beijing Shunyi District Hospital, Beijing Changping District Hospital and Beijing Liangxiang Hospital) in Beijing from November 2018 to November 2019. Eligible patients were those aged ≥ 65 years with hip fracture confirmed by X-ray and being admitted to hospital within 21 days of injury. To explore the epidemiological characteristics of geriatric hip fractures in Beijing, such data were collected as patients' age, gender, comorbidities, as well as type, site, time and cause of the fracture.Results:① A total of 2,071 patients were included in this suevey. They were 653 males and 1,418 females (M∶F=1∶2.17). Their age ranged from 65 to 102 years (average, 79.8 years). The patients aged from 75 to 84 years were the most common, accounting for 44.81% (928/2,071). ② Femoral neck fractures accounted for 43.41% (899/2,071), and intertrochanteric fractures accounted for 56.59% (1,172/2,071). The age of the patients with femoral neck fracture was (78.6±7.7) years, which was significantly younger than that of those with intertrochanteric fracture [(80.7±7.4) years] ( P<0.05). ③ 94.69% of the hip fractures (1,961/2,071) were caused by falling, and 71.27% fractures (1,476/2,071) happened at home. ④ Approximately 83.00% of the patients (1,719/2,071) had one or more comorbid conditions. Hypertension was the most prevalent disease (57.89%, 1,199/2,071), followed by diabetes (27.09%, 561/2,071), and coronary atherosclerotic heart disease (22.02%, 456/2,071). Conclusions:In Beijing, significantly more geriatric females sustain a hip fracture than males, and the proportion of those aged from 75 to 84 year is the largest. The proportion of intertrochanteric fractures increases with age. Falls are the leading cause for geriatric hip fractures. Most of the patients have one or more chronic comorbid conditions. Corresponding prevention and intervention measures should be formulated according to the distribution characteristics of elderly hip fractures in Beijing.

Objective To analyze the etiological characteristics of human Brucella strains isolated, and to improve the precision in control and prevention of brucellosis. Methods In 2016, blood samples were collected from patients in Jingyuan County Gansu Province, and tested via the Rose-Bengal Plate Agglutination Test (RBPT) and the tube agglutination test methods,and serological positive blood samples were inoculated to bidirectional blood culture bottle for culturing, and further identified by traditional biological classification method and the Brucella abortus, Brucella melitensis, Brucella ovis, and Brucella suis species-specific PCR (AMOS-PCR). Multiple-locus variable number tandem repeat sequence analysis (MLVA) -16 was used to detect molecular typing and do cluster analysis. Results The isolated strain was identified by the traditional biological classification method, bacteria could grow in thionine and reddened dye, A and M factors agglutination tests were positive, Bk2phage treatment of bacterial strain cracking, but Tb, Wb phages were not cracked. AMOS-PCR amplification result showed a 731 bp band, which was a strain of Brucella melitensis. The results of MLVA-16 showed that there was a difference in the number of repeats on some Variaable Number of Tandem Repeat(VNTR)sites of the isolated strain. Clustering analysis showed that, the isolated strain was clusted into the same clade with the clustering of Brucella melitensis type 3 from GS-201605 in Gansu. And the clustering was similar compared with that of Zhejiang, Guangdong, Fujian and Yunnan. Conclusion Human brucellosis is a inputting transmission in Gansu Province, there is a genetic variation of genotype 3 sheep Brucella between Gansu Province and other domestic provinces.

Objective To investigate the rate of awareness of chronic kidney disease(CKD)among non-urology physicians from certain tertiary hospitals,second-level hospitals and community hospitals,so as to explore ways of early identification and preven-tion of CKD.Methods A questionnaire survey with the help of Wechart platform was performed in 94 non-urology physicians from 5 tertiary hospitals,4 second-level hospitals and 25 community hospitals.Topics of the survey included CKD high-risk population,CKD initial manifestations,CKD deterioration factors and other indicators,and then,analyses of the obtained results were made in the study. Results Full awareness rate of CKD high risk population by physicians was 57.45%,and the full awareness rate of initial manifesta-tions by physicians was 21.28%,with the physicians from community hospitals having the lowest rate, accounting for 19.74%.The full awareness rate of CKD deterioration factors by physicians was 51.06%, with the physicians from community hospitals having the lowest rate,accounting for 46.05%.The full awareness rate of CKD reversible factors by physicians was 51.06%,with the physicians from community hospitals also having the lowest rate, accounting for 44.74%.The full knowledge rate of CKD detection methods by physicians was 68.09%, the knowledge rate of CKD stage classification by physicians was 35.11%, that of CKD early intervention measures by physicians was 81.91%,and that of CKD routine detection methods for renal function was only 38.30%.In 94 non-urolo-gy physicians,only 36% of the physicians received training on related knowledge of CKD, and 64% of the physicians never received any training in this respect.Conclusion Deficiency in the awareness or knowledge about CKD prevention and treatment among non -u-rology physicians is quite popular in the country.For this reason,efforts should be made on the training,so that physicians will have better knowledge about CKD,and consequently the rate of awareness and knowledge about CKD,the rate of early diagnosis,as well as the cure and control rate of CKD could be greatly enhanced.

Non-alcoholic fatty liver disease (NAFLD) has become one of the major metabolic diseases.In view of the defects of traditional animal models, this study was the first to establish the NAFLD model of Mongolian gerbil (Meriones unguiculatus) with simple feed formula which is similar to human (from simple fatty liver to steatohepatitis, fibrosis,Liver cirrhosis).This study discussed the mechanism of rapid fatty liver deposition in Mongolian gerbil, revealed its molecular mechanism,main regulatory target and network function of fatty liver susceptibility.We provide a new animal model of NAFLD with relatively clear background and less time-consuming for clinical treatment and new drug development.The theoretical and practical basis for the breeding of inbred strain NAFLD gerbil was established.
